vPro1 A Major TB1 revision

Between version 12 and what would have been version 15 we came up with a great many additions, clarifications, modifications, reformatting and reorganization – and a couple of corrections too.  There was sucn a big change – an this will be it for a long long time I think – that begining with this revision I am assigning an entirely new revision sequence: welcome to vPro1.

By the way, if you find this site useful please let your Python friends know about it. I make no attempt at SEO (I’m retired and work on a shoestring). Thanks for taking a moment to pass it on.

PS. a very minor format error caused by a bug in Publisher has been fixed on the GitHub download as of 5:50 EST USA 7/13/17.
